I have seen that video of the eland several times and will say that any regular broadhead placed in the same place would have done the same thing but would have likely penetrated quite a bit farther than that bloodrunner did. That massively thick ferrell is not conducive to good penetration, especially through bone.

Here is one with a rifle shot.
